Abstract: An elevator has a safety control unit that distinguishes between a first input signal and a second input signal at an input for selecting an operating mode. The elevator has a main switch device with a switch, the main switch device being accessible from outside a shaft of the elevator. The main switch device and the safety control unit are connected, wherein the switch is switchable from a first state into a second state. The safety control unit operates in a first operating mode when the switch is in the first state, in a second operating mode when the switch is in the second state and the safety control unit detects the first input signal at the input, and in a third operating mode when the switch is switched to the second state and the safety control unit detects the second input signal at the input.
