COMPONENTS ( Con’t )
HIGH LIMIT SWITCH
VDSC305-VDSC365-VDSC485(RH)
VDSC485(LH)-VESC305-VESO105-VEDO205
Function: The Switch has a ½ “ bi-metal
disc. The two metals have different thermal
coefficients of expansion which cause the disc
to bow as it heats up. When it reaches the
calibration temperature the disc snaps open,
which opens the electrical contacts. The
Switch opens when temperature reaches 275*
F plus or minus 9*F and will close when
temperatures are 248* F plus or minus 9*F.
COOLING FAN LIMIT SWITCH
VDSC305-VDSC365-VDSC485(RH)-
VDSC485(LH)-VESC305-VESO105-VEDO205
Function: The Switch has a ½ “ bi-metal disc.
The two metals have different thermal
coefficients of expansion which cause the disc
to bow as it heats up. When it reaches the
calibration temperature the disc snaps closed,
which closes the electrical contacts. The
Switch closes when temperatures reach 230* F
plus or minus 9* F and will open when
temperatures are below 203* F plus or minus
9*F.
SELECTOR SWITCH (8 POS) (PJ030001)
VDSC305-VDSC365-VDSC485(RH)-VESC305-
VESO105-VEDO205
Function: Rotating the shaft twists a cam
which moves one or more spring loaded
levers, which make contact with a terminal
closing the circuit.
SELECTOR SWITCH (PJ030009)
VDSC485(LH)
SELECTOR SWITCH (3 POS) (PJ030010)
VESO105-VEDO205
OVEN THERMOSTAT
VDSC305-VDSC365-VDSC485(RH)-
VDSC485(LH)-VESC305-VESO105-VEDO205
Function: As the shaft is rotated from the OFF
position clockwise, an internal cam pushes a
lever, which increases the temperature at
which the thermostat cycles. Rotating the
shaft 212* (angle *) switches an external
(clean) Micro Switch to the closed position.
