FEATURES
• Realizes miniaturization of equipment
and spaces saving. Size of body:
9.5×9.5×9.3 mm
• The contact type is equivalent to
normally closed contacts, which satisfies
the PL Act.
• The internal sphere can be used over
an operation angle of 360 degrees in the
circumferential direction.
• There are three standard terminal
profiles which can be selected according
to the mounting direction of the PCB.
• The terminals are tin-plated for long-
term solderability.
TYPICAL
APPLICATIONS
• Gas heaters
• Electric fans
• Water vallet
• Infrared treatment device
• Electric pots with warming function
