Abstract: The invention relates to a safety device (1) for the emergency deactivation of an electrical water heater or a heat pump, wherein the safety device (1) comprises at least one contact pair (70, 80, 90) having at least one first contact assembly (71, 81, 91) and at least one second contact assembly (72, 82, 92), which are designed to direct the current to supply the water heater or the heat pump in a contacted state, and to interrupt the current supply to the water heater or the heat pump in an open state, as well as comprising a retaining device (94) for retaining the second contact assembly (72, 82, 92) on a tension rod (40), wherein the tension rod (40) is designed to release the retaining device (94) and the second contact assembly (72, 82, 92) from the first contact assembly (71, 81, 91) in order to interrupt a current supply to the water heater or the heat pump.

Abstract: A safety device for emergency shut-down of an electric instantaneous water heater. The safety device includes a contact and a counter contact, which are set up to conduct the current for supplying the instantaneous water heater in a contacted state and to interrupt the power supply of the instantaneous water heater in an open state. Further, the safety device includes a mounting device for mounting the counter contact on a tie rod, wherein the tie rod is set up to release the mounting device and the counter contact 4 from the contact to interrupt a power supply of the instantaneous water heater. The contact of the safety device is implemented as a contact rivet which is integrated directly into a circuit board.
