Provided is an electric switch, including a casing, an actuator, a movable contact frame, a snap-action resilient member, a lock mechanism, a signal switch and a contact switch. The actuator is capable of reciprocating along a first direction. The movable contact frame is provided with a retaining portion. The snap-action resilient member is arranged in the movable contact frame and is compressed by the actuator when the actuator moves. The lock mechanism includes two lock members which are capable of reciprocating in the mounting cavity along a second direction with the movement of the actuator, so as to lock or unlock the retaining portion. A brush of the electric switch is arranged on the movable contact frame. A movable contact of the contact switch is arranged on the movable contact frame.

A waterproof switch device and a waterproof switch module for a vehicle trunk door employing the same are disclosed. Without using a PCB, terminal leads and a pair of switch terminal parts providing switch terminals are integrated with the switch bracket by injection molding. A push button unit is capable of switching the exposed switch terminals and is also sealingly coupled to the top side of the switch bracket so that the space containing the switch terminals and the switch contacts is waterproof. The lead portions of the switch terminals and the switch cables are connected in the terminal receiving space of the switch bracket, and the waterproofing part fills the terminal receiving space so that they are completely embedded so as to be waterproof. The waterproof switch module for a vehicle trunk door adopts the waterproof switch device and is composed of a double waterproof structure by applying an additional waterproof structure.

An entry sensor, which supports either wireless or wired operation, facilitates installation and is adjustable for gaps between a building entry barrier such as a door or window and the surrounding frame. The sensor, which may be implemented as a single piece design, includes an adjustment mechanism that enables an installer to vary the extension of the sensor to match the actual gap so that the sensor properly secures the building entry when closed. The sensor includes a detector that determines the state of a switch that is responsive to the movement of a plunger mechanism, where the state is indicative whether the building entry barrier is opened or closed, and that may determine whether the sensor is tampered with. The sensor also may facilitate battery replacement that protects the associated circuitry during the replacement.

A door latch device includes: a first position switch and a second position switch, each including a first contact hole, a second contact hole, and a common contact hole; a common pin configured to be electrically conducted to the common contact hole of the first position switch and the first contact hole of the second position switch by being inserted therein; a first signal pin configured to be electrically conducted to the first contact hole of the first position switch by being inserted therein; and a second signal pin configured to be electrically conducted to the common contact of the second position switch by being inserted therein, wherein the first position switch and the second position switch are configured to perform a switch operation at a same timing of an operation of a predetermined operation detection target.

A three-way switch associated with an entry point barrier may provide a security system with information regarding a position of the entry point barrier as it moves along a path of travel. As the entry point barrier moves, the three-way switch may come into proximity with an external object, and the three-way switch may indicate to the security system that a circuit associated with the three-way switch has been closed. The security system may determine that the entry point barrier is in a given position, and one or more security system policies associated with the given position may be activated.

A swipe gesture detection device may determine a swipe gesture performed on a moving surface element of a vehicle component. The swipe gesture detection device includes a spring, which applies a pre-loading between the moving surface element and a housing element of the vehicle component. The swipe gesture detection device also includes a contactless measuring distance sensor having at least three sensor elements arranged in different positions for detecting a respective distance between the surface element and the housing element.
