Abstract (en)
A modular auxiliary switch (100) comprises a mechanism (18) for controlling at least one interruptor (16) with inverting contacts (32, 34, 36), and a manual test device (70) intended to check the operation of the elements inserted into the auxiliary electrical circuit, without change of state of the associated circuit breaker block. The test device (70) comprises a test button (76) and a control lever (72) acting directly on the moving contact (32) when the test button (76) is depressed, in order to cause the forced switching of the interruptor (16), independently of the mechanism (18) which remains stationary. After the test button (76) has been released, the lever (72) returns automatically to an inactive position thanks to the return action of a spring (78). This device avoids the local resetting of the mechanism (18) after the test. <IMAGE>
