•
The above model is referring the 'A8GS-S1100'.
•
No reset function models are without coil circuit.
•
Specifications are same with reset function models.
Note: 1.
Unless otherwise specified, a tolerance of ± 0.4 mm applies to all dimensions.
Note: 2.
When initial operation or operation after reset, operating force is increased, due to switch structure.
Note: 3.
TV-8 approved models are same outline and characteristics with standard models.
* Solder terminals model has different hole shape, compare with Quick-connect terminals. Outline and characteristics are same.
