An electric switch for a power tool, comprising: a slider slidably received in a switch casing along a longitudinal direction, a handle provided in the grip of the power tool for manually actuating the slider along the longitudinal direction; a plurality of fixed contact pieces arranged in an internal bottom surface of the switch casing and provided with contact surfaces located substantially in a same plane; and a plurality of moveable contact pieces arranged in the bottom surface of the slider and urged toward the fixed contact pieces by spring members so as to selectively contact at least some of the contact surfaces of the fixed contact pieces. The contact portions of this switch achieve various conductive states by planar arrangement and movement of the contact pieces, the component parts can be fitted into a small switch casing, particularly having a small height. Since the component parts may be assembled one over the other in sequential manner without requiring special efforts, a substantial advantage can be gained in the improvement of the efficiency of the assembling process. And, these advantages can be gained without diminishing the reliability of the various states of contact between the various contact pieces.

Electric switch for a power tool

A slide switch comprising a box-shaped housing base member, a switching contact mechanism housed within the base member, an electrically insulating flexible film member having an external configuration permitting it to be housed within the base member, a striker mounted on the film member, and a cover member mounted on the base member.

Slide switch

A switch comprising a cylindrical housing, an actuator mechanism disposed at one end of the housing for contacting an object to be sensed by the switch, a plunger slidably housed within the housing for receiving a displacement by the actuator mechanism, and a switching mechanism associated with the plunger for switching a circuit in accordance with the actuation by the plunger. The actuator mechanism includes a conical supporting member tiltably engaged with a flange member formed in the aforesaid one end of the housing.
