[0024] In implementation, the number of transverse guide grooves 3, conductive metal strips 4 and bosses 7 is determined according to the number of travel switches 9. For example, a travel switch 9 with break and close functions usually has three contacts. At this time, three transverse guide grooves 3, three conductive metal strips 4 and three bosses 7 are connected as a group to the contacts of one travel switch 9, and the number of transverse guide grooves 3, conductive metal strips 4 and bosses 7 is three times the number of travel switches 9.
