ABSTRACT:
A non-magnetic plate, or spacer block, of is attached to the side of the switching assembly of a high security switch system. Alternatively, the actuator assembly may have an extended housing. As a result, a second actuator assembly may not be substituted for the first actuator assembly by placing the second actuator assembly on the side of the first actuator assembly and slid under the security switch assembly as the first actuator assembly is moved away for the purpose of defeating the security switch.
