Abstract
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.
Claims12
A switch, comprising:
- a cylindrical housing having a fixed flange member formed at one end, said flange member having a conical surface,
- actuator means disposed at said one end of the housing for contacting an object to be sensed by the switch,
- plunger means slidably housed within the housing and slidable within said housing responsive to a displacement of the actuator means, and
- switching means in contact with the plunger means, said switching means being actuatable to switch a circuit contact means responsive to displacement of the plunger means,
- said actuator means including a conical supporting member having one surface in contact with said plunger means and an opposite conical surface tiltably engageable with said conical surface of said flange member.
