Abstract
A fluid operated electrical switch construction having a first housing provided with an electrical switch therein and a second housing having an expandible and contractible fluid operated power element therein, the housings being secured together in a predetermined assembled relationship so that a motion transmitting arrangement is disposed in both of the housings and extends between the power element and the switch to transmit movement of the element to the switch to operate the same. The motion transmitting arrangement has a length adjustment unit therein that is adapted to be adjusted by first causing relative movement between the housings while the housings are assembled together but before the same are secured together so that once the adjustment unit has been adjusted to provide the proper length, the housings are secured together in such assembled relation.
