A switch mechanism includes a housing with a fenestration, a switch element held in the housing, and a first tab and a second tab each being pivotally attached to an opposite lateral edge of the fenestration. The tabs are constrained to rotational movement relative to the housing so that contact with the first tab or the second tab causes the respective tab to rotate to actuate the switch element.

A resin structure includes a molded resin element and a push-type switch. The push-type switch includes a receptacle whereon a first terminal and a second terminal are secured, the first terminal and the second terminal configured to connect to an electrical circuit; a button unit protruding from the receptacle; and a contact spring unit configured to move with the button unit, to electrically connect between the first terminal and the second terminal, and to generate an opposing force relative to a pressure applied between the receptacle and the button unit. The receptacle stores the button unit and the contact spring unit. The receptacle of the push-type switch is embedded in the molded resin element with the button unit exposed from the molded resin element.

A test switch for use in electrical power distribution networks is provided. The test switch facilitates the connection between the power distribution networks' equipment and test equipment used to effect tests on the power distribution networks' equipment. The test switch has a solidifying base which decouples the fastening of the body of the switch to the base of the test switch from the fastening of the test switch on an external surface/equipment. Various locking mechanisms for preventing use of or tampering with the test switch are also provided.

Various embodiments of a compression activated switch device for holding light emitting packages are provided. The device includes an electrical switch configured to operatively couple between a light emitting package and a power source. The light emitting package includes a light emitting element on a support, the electrical switch biased to an open position from a closed position. The compression activated switch also includes a coupling component configured to couple the light emitting package to a structure and a biasing element biasing against coupling the light emitting package to the structure with a predetermined force, wherein in response to a force being applied to the coupling component sufficient to overcome the predetermined force the electric switch moves to the closed position. Visual or audible feedback may be provided upon the application of the predetermined amount of force.

A power tool (1) includes an electric motor (2) as a drive source and a start switch (20; 61) that starts the electric motor (2) and is lockable in an ON position in a lock-ON state. An electromagnetic actuator (30; 40; 50; 60) pushes out or pulls in an actuation pin (30a; 40a; 50a; 60a) with respect to a body of the electromagnetic actuator (30; 40; 50; 60) in response to cutting off of a supply of electrical current to the power tool (1). The pushed-out or pulled-in actuation pin, directly or indirectly, disengages the start switch (20; 61) from the lock-ON state and/or prevents the start switch (20; 61) from being shifted into the lock-ON state.
