PURPOSE:To facilitate the discrimination of contact operation, by merely attaching a plurality of inspection rods in a parallelly inserted state from the lateral side in the vicinity of the contact table in a contact plate. CONSTITUTION:In a time switch, inspection parts 28 in each inspection rod 26 of a connector 23 are inserted into the performations 13a-13c of a contact table 8. By this constitution, contact parts 28' are advanced toward touch parts 11a- 11c to be contacted therewith. When a main shaft 3 is revolved in this state, a cam 4 is also revolved while switches 7 are operated and a contact 15 is contacted and separated. Therefore, the electric signal due to the contact and the separation of the contact 15 is taken by the inspection rod 26 through a contact plate 10 and reaches a program inspector 21. By this inspection result, the discrimination of contact operation can be easily detected. |
