Abstract
An industrial locking switch comprises multiple locking tongue entry slots formed on adjacent sides of the locking switch housing, thereby supporting receipt of the corresponding locking tongue from multiple directions of approach without the need to mechanically modify the switch's head or to reorient the switch itself. The locking switch houses locking bolt detection circuity comprising multiple series connected RFID coils configured to detect an RFID tag mounted on the locking tongue when the locking tongue is inserted into any of the entry slots.
