MIL-PRF-24236/19L
Salt spray (corrosion): In accordance with MIL-PRF-24236, except switches shall be subjected to and pass the
seal test after undergoing salt spray.
NOTE: Destructive corrosion shall be construed as any type of corrosion which in any way interferes with the
mechanical or electrical performance of the switch, or corrosion which causes seal failure.
Marking: Identification marking shall be placed on the unit package label or tag.
Extent of qualification: See table IV.
Part or Identifying Number(PIN): PINs shall be assigned as illustrated below:

Configuration and contact action (see table I)
Coarse high temperature setting
to within 20°F (see table II)
Fine high temperature setting
to within 5°F (see table III)
Add the letter "L" when low level is required
NOTE: PIN M24236/19-AHCL identifies a switch that closes on increasing temperature at 120°F ±8°F with a
temperature differential of 30°F ±8°F with low level capabilities.

For switches that operate as follows:
a. Close on increasing temperature; contacts close at high temperature setting and
open at high temperature setting less 30°F differential temperature.
b. Close on decreasing temperature; contacts close at high temperature setting
less 30°F differential temperature and open at high temperature setting.
c. Open on increasing temperature; contacts open at high temperature setting and
close at high temperature setting less 30°F differential temperature setting.
d. Open on decreasing temperature; contacts open at high temperature setting
less 30°F differential temperature and close at high temperature setting.
