Improved pilot devices having inserts comprising a spring-loaded stirrup for clamping electrical conductors, together with a screw for adjusting the clamping action of the stirrup and for releasably locking the stirrup in a fully open position to permit insertion of an electrical conductor, a mechanism for quickly and easily releasing the stirrup when the conductor is in a desired position, and an attachment member for releasably securing the block to a mounting rail. Also, included are independent bus bars which can be selectively operated to create an open or closed circuit condition between two different spring-loaded stirrups in the pilot device.
