Abstract

Some implementations require simple detection of which 180 degrees sector of rotation the shaft occupies. A switch is illustrated for this purpose. The switch consists of a case 10 enclosing two contact terminals 12, 14 and two wire contacts 16, 18.

Shaft Position Detector Switch

Some implementations require simple detection of which 180 degrees sector of rotation the shaft occupies. A switch is illustrated for this purpose. The switch consists of a case 10 enclosing two contact terminals 12, 14 and two wire contacts 16, 18.

A cam surface 20 on the rotatable shaft 22 actuates the switch by driving the wire contact 16 onto the contact terminal 14. Actuator linkage is eliminated and direct actuation accomplished by the flapper 24, which is an integral part of the case 10. The use of two redundant wire contacts can produce high-switching reliability.
