The switch is not made to stay in. My understanding of the circuit is the switch sends current to a Cap. The Cap is charged and holds down a relay for around 10 min. till current drops down to where the relay releases. You might want to check the relay/Cap to see if it has failed (But I can’t tell you where it is, I need to get a good Elec. drawing for a C900). Hopes this helps.
