(1) Miniature snap switches tted with a lever are supplied with the lever xed in position B (see page 48). For basic (plunger) snap switches, it is possible to x the
lever in position A, B or C, depending on the required tripping conditions (see page 48).
(2) Position of the operator in relation to the switch xings (xing hole centre line) at the instant the switch contact changes state.
