Because the A22TK safety key selector switch uses the same key as the guard lock safety-door switch, the operator is prevented from forgetting to remove the key. The result is a safer working environment when performing maintenance.

Because the A22TK safety key selector switch uses the same key as the guard lock safety-door switch, the operator is prevented from forgetting to remove the key. The result is a safer working environment when performing maintenance.
*To unify keys, specify the same key type.
With the Selector Switch, it is possible to switch between normal operation mode (use of Door Switch is available) and maintenance mode (use of Enabling Grip Switch is available).

Note: 1. Rated current values are determined according to the testing conditions. The above ratings were obtained by
conducting tests under thefollowing conditions.
(1) Ambient temperature: 20±2C°
(2) Ambient humidity: 65±5% RH
(3)Operating frequency: 20 operations/minute
2. Minimum applicable load: 10 mA at 5 VDC

PTI (tracking characteristic) | 175 | |
Degree of contamination | 3 (EN60947-5-1) |
*1. Malfunction within 1 ms.
*2. With no icing or condensation.
*3. The degree of protection from the front of the panel.
Note: 1. Do not allow the load current to exceed the rated value.
2. The contact ON/OFF timing is not synchronized. Confirm performance before application.
3. Once the contacts have been used to switch a load, however, they cannot be used to switch smaller loads. The
contact surfaces will become rough once they have been used and contact reliability for smaller loads may be
reduced.
