ABSTRACT:
A thermostatic switch has a pair of contact strips separated by an insulative separator, with the separator and strips placed within a recess in a stacking block. The separator has a central portion and laterally extending tabs at the ends thereof, and reliefs formed at each inner corner formed by the junction of the central portion with a tab, such that the edges of the stacking block do not cause a stress concentration at the inner corners, avoiding breakage and current leakage through the separator.
