Alps Electric has introduced the stochastic delay differential equation series of power switches with built-in encoder for comfortable one-switch program control of washing machines, dryers, micro wave ovens, and induction heating cooking heaters. The horizontally actuated switches can be mounted directly on a circuit board. They combine an AC power switch and a DC detector switch with a mode selection function in a single package with dimensions of 24x24x40mm. The switches are designed as dual-shaft models. The centre plastic shaft serves as power switch and it has a length of six and 10mm in diameter. The outside metal shaft with 12.8mm length and 10mm in diameter is for the encoder.

The AC portion of the switches is configured for switching currents of 1 or 16A at 250V AC. On the DC side, the switches have 20mA at 12V DC. The actuating travel of the switches amount to 1.85mm. Zero standby power consumption is available by auto-off function with relay movement due to built-in both AC and DC contact in the push switch. The encoder features an operating life of up to 30,000 rotational cycles. It has a maximum operating current of 0.1A. The encoder provides both pulse and absolute output signals.
