A switch actuating device (1) for a vehicle door includes an actuating element (10) with an actuating surface (11), a mechanical switch (20) and a mechanism (30). The switch is secured on a first component/component group (31). A lever (32) is mounted for pivot in relation to the first component/component group (31). A first region (32.2) of the lever is connected to a first part of the actuating element (10) via a first articulation (10.1). A second part of the actuating element (10) is mounted on the first component/component group (31) via a second articulation (10.2). The actuating element (10) bends when the actuating surface (11) is subjected to manual pressure causing the distance between the first articulation (10.1) and the second articulation (10.2) to shorten, which causes the lever (32) to pivot toward the switch such that the switch is switched.

The disclosure provides a switch assembly and an electric drill. The switch assembly includes a first switch, a button, and a locking mechanism. The button is provided with a pressing part that cooperates with the first switch, so as to trigger the first switch when the button is pressed. The locking mechanism includes a locking member for locking the button and a trigger pivotally mounted and matched with the locking member. When the locking mechanism is locked, the locking member resists the button, so that the button cannot be pressed. When the trigger is rotated, the trigger drives the locking member to move, so that the locking member is misaligned with the button, and the button can be pressed at this time.

A trigger assembly having: a housing with a switch; a trigger; an actuator movable from OFF wherein the switch is operably-opened, towards ON wherein the switch is operably-closed; a lock-on mechanism including a first locking member mounted proximate the trigger and a second locking member mounted proximate the housing; when the actuator is ON, said locking members are movable relative to each other into a locked configuration; a lock-off mechanism including a lock-off member that is movable about a rotation axis between locked-off-position, which restricts movement of the trigger and the actuator is restricted from movement, and non-locked-off-position, which does not restrict movement of the trigger and the actuator member is not restricted from movement; and a shaped-portion disposed proximate the housing that abuts the lock-off member when the trigger is moved towards the housing with the lock-off member in the locked-off-position, whereby the actuator is restricted from movement.

The present teachings provide for a device with a membrane and an underlying switch, an underlying switch actuator, or both that has a unique tactile pattern that is felt through the membrane when the membrane is aligned with the switch, switch actuator, or both, corresponding to the electrical state of the device. The membrane, the switch, the switch actuator or a combination thereof can be repositioned from a first position to a second position so that a different tactile feel is present through the membrane corresponding to a second electrical state.

A power tool includes a motor and a power supply that are connected by a switch disposed in an electrical circuit. The switch controls the on/off state of the motor and is actuated by a switch actuator that serves as a spring element. The switch actuator includes a guide plate supported on the housing, and a resilient arm that protrudes from the guide plate into an opening in the tool housing. When the switch actuator is in a first actuator position relative to the housing, the resilient arm is biased toward an edge of the opening and engages the edge, thereby preventing inadvertent movement of the switch actuator to the second actuator position. When the switch actuator is actuated by applying a bi-directional manual force to the resilient arm, the resilient arm is displaced from the edge, thereby permitting movement of the switch actuator to the second actuator position.

An electric actuator includes a housing, an electric driving unit, an selector member being rotatable about a rotation axis and moving in a direction of the rotation axis, a position holding member and detection object provided in the selector member, a detector, an engagement groove provided on a cooperation surface inside the housing, and a biasing member biasing the selector member in the direction of the rotation axis to make the position holding member approach the cooperation surface. The engagement groove is formed so that the detection object is positioned in one of a detectable area and an undetectable area when the position holding member is engaged with the engagement groove, and the detector is configured to switch between supply and cutoff of power to the electric driving unit in accordance with whether or not the detection object is detected.

A switch assembly, a switch assembly starting method and a power tool are provided. The switch assembly includes a housing, a main control switch accommodated in the housing, a locking switch and a trigger switch arranged on the housing. An end of the trigger switch is accommodated in the housing and is in contact with the main control switch. An end of the locking switch is in contact with the trigger switch. The locking switch has a locking position and a releasing position, when the locking switch is in the locking position, the locking switch limits the trigger switch in a locked state, and the main control switch cannot be started; when the locking switch is in the releasing position, the locking switch is positioned beside the trigger switch and limits are removed, the trigger switch is in the release state, and the main control switch can be started.
