Abstract
A conductive member of plate form is supported on a spring biased member into a static postion of contact at a first corner with a support surface and at a second adjacent corner with a first contact member. A load applying member makes contact with the conductive member on the side thereof opposite from the spring biased support. A low rising pressure acting through the load applying member swings the conductive member in position about a first axis defined by its locations of contact with the support surface and the first contact member into a position in which it also contacts a second contact member and completes a conductive path between the two contact members. An intermediate rising pressure signal causes the conductive member to swing in position about a second axis defined by its locations of contact with the two contact members and against the operator of a micro-switch. A high rising pressure signal causes the conductive member to swing in position about a third axis defined by its locations of contact with the operator of the micro-switch and with the second contact member and move out of contact with the first contact member, to in that manner open the conductive path between the two contact members.
