if button is operated to turn OFF, and Switch is turned OFF by external
signal.
• Zero standby power with Reset function, switching OFF by external signal.
• Preventing from application trouble such as a data lost or circuit damage
by forced power OFF.
• Timing control of main power switch turn OFF for safety application
design with Delay OFF function.
• Contact gap of 3 mm minimum.
• UL and cUL standard approved, Conforming to EN standards.
RoHS Compliant
(Please refer the Precautions)
Usage example

Operation
Delay OFF Function
Power contacts are kept in ON status, even if button is operated to turn OFF by manual operation of button.
And Switch is turned OFF by external signal to coil embedded in switch.
(1) Signal contact terminal and Power contact terminal are turned ON by manual operation of button.
(2) Power contact terminal is kept in ON status, even if button is operated to turn OFF by manual operation.
Only Signal contact terminal is turned OFF.
(3) Power contact terminal is turned OFF when external signal is applied to coil.
Furthermore, it is able to turn OFF both signal and power contact terminals from manual ON condition at the same time by
applying voltage to coil as Remote Reset Function.

At initial operation or operation after reset, operating force is increased, due to switch structure.
Solder terminals model has different hole shape, comparing with Quick-connect terminals. Outline and characteristics are same.
No models of switch without delay off function (without coil), due to product design.
Panel Cutout
Panel thickness: 0.8 to 2.3 mm
Panel cutout design is for prevention of false insertion.
Please be careful about the direction of the protrusion.
The rollover of the panel shall be on the front face.
And panel back side shall be Edge shape by processing.

5月15日，美国宣布将推出新的出口管制规定以扩大对华为的“封锁”。这一规则扩大了实体清单的范围，无论是否是美国公司，只要是使用到美国的技术，设备等向华为出货都需要许可证。 对此，美国半导体协会（SIA）总裁兼CEO John Neuffer发表声明称：“我们担心这一规则可能会对全球半导体供应链造成不确定性和破坏，但它对美国半导体行业的损害似乎比之前考虑的非常广泛的方法要小。” ...[详细]
