A typical automatic control utilising contact S1 (the process monitoring contact e.g. Thermostat, float switch, limit switch) to control a contactor (coil KM1) to switch a motor is shown below;. In order to implement manual override, a three position selector switch; S2 (e.g. Schneider Electric Harmony type ZB4BD3 + ZB4BZ103) is utilised as shown in the circuit diagram below; The 'stay put' selector switch has 2 qty N/O (normally open) contacts;. The N/O contact in position 1 ('Auto' control) is wired in series with contact S1 to enable automatic control. The N/O contact in position 3 ('Manual' control) is wired in parallel with contact S1 overriding the automatic control and therefore maintaining the operation of the contactor.
