ABSTRACT:
An apparatus comprising a plurality of electric switches, pneumatic actuators for the switches, assemblies for preventing inadvertent actuation of one or more switches and supports for the elements of the assemblies in coactive relation to each other, in such a way as to prevent eventual binding of the spring arm retainer. This apparatus further eliminates the need for molding of the retainer plate or the separate molding of the supports leading to a reduction in cost and assembly time.
