An illuminated keyswitch includes a base, a keycap, a lift mechanism, and a light source. The keycap includes a cap body and a light guiding rod. The lift mechanism is connected to between the light guiding rod and the base, such that the keycap can vertically move relative to the base through the lift mechanism. The light source is disposed between the light guiding rod and the base and emits light toward the light guiding rod. The light enters the light guiding rod through an end portion of the light guiding rod and then emits out the light guiding rod from another end portion of the light guiding rod and a side surface adjacent to the another end portion toward the cap body. Thereby, the whole cap body can receives relatively uniform back light.

An operating device includes a push operation mechanism to be push-operated by an operator, and a drive transmission mechanism to transmit a drive force for presenting the operator with a tactile stimuli-operational feeling via the push operation mechanism. The push operation mechanism is configured to be engageable with the drive transmission mechanism. The drive transmission mechanism is configured to switch between a non-engagement position to allow the push operation of the user without being engaged with the push operation mechanism and an engagement position to allow the transmission of the drive force by being engaged with the push operation mechanism.

An ignition switch assembly is configured to be operatively connected to a gas valve. The ignition switch assembly may include a first ignition contact and a second ignition contact. The first and second ignition contacts may be sized and shaped the same. A hub may be configured to be rotated within the ignition switch assembly. A rotation of the hub in a first direction causes a portion of the first ignition contact to engage the second ignition contact. Further rotation of the hub in the first direction or rotation of the hub in a second direction that is opposite from the first direction causes the portion of the first ignition contact to disengage from the second ignition contact.

A control element having a beam member divided into an actuation section and a valve section positioned on opposing sides of a pivot member, in which active control of the actuation section causes buckling of the valve section to bring the valve section from a closed state to an open state or causes relaxing of the valve section to bring the valve section from an open state to a closed state.

A diverter switch is for an on-load tap-changer. The diverter switch includes: at least one vacuum interrupter; an actuating element, which is mechanically connected at a first end of the vacuum interrupter and has a roller at a second end; and an actuating body having a base body and having at least one cam. The vacuum interrupter is configured to be actuated via the actuating element as a result of the roller moving over the actuating body. At least one part of the cam has a higher strength than the base body.

A switch (30) for a hand-held power tool (10) or as a component of a hand-held power tool (10), which has an electric drive motor (16) that can be switched by the switch (30). The switch (30) has a switch housing (33) with a switch chamber (35) in which a switch actuator (75) that can be moved between at least two switch positions (ML, MR) is arranged in order to actuate an electric switch element, said switch actuator being kinetically coupled, by means of a transmission element (70), to a switch (30) actuation element (32), which is arranged outside the switch housing (33) and can be moved between at least two actuation positions (R, L), wherein the transmission element (70) passes through a through-opening (54) on a wall of the switch housing (33) such that the switch actuator (75) can be moved by moving the actuation element (32) in order to actuate the switch element (24). A rotary bearing (77) is arranged in the through-opening (54), the transmission element (70) being rotatably mounted on the rotary bearing about a rotational axis (D).

Key switches of the inventive subject matter are designed to give users the tactile feel of key switches from expensive mechanical keyboards without drawback typically associated with alternative key switches. In some embodiments, key switches described in this application are designed to function with a sheet of membrane switches, while in other embodiments, key switches of the inventive subject matter incorporate optical switching in place of membrane switching. Embodiments for use with membrane switching feature a plunger and rocker combination that prevents the pressure from a user's key press from being directly transferred to a membrane switch, thereby reducing wear and tear. In optical switching embodiments, pressing the key switch causes an actuator, e.g., come between an optical emitter/receiver pair to register a key press.
