The '''Clare/Pendar low profile reed''' series comprises the short [[reed]] keyboard switches from Clare and Pendar in Europe. The North American counterpart is [[Clare-Pendar Series S880]]. In the ordering information section of EFL's catalogue, the term "'''SFL Series'''" is also used to cover the whole series, but this is ambiguous at best.

==Description==
The low-profile reed switches share the same PCB and plate dimensions as [[Clare/Pendar high profile reed]]. Illumination can be provided using either an LED or an incandescent bulb. The keystem angle for stepped switches is 11°.

The series appears to have gone out of production with the bankruptcy of [[ESM]] in 2015.

==Product range==
The product range was divided into three sub-series:

;SFL
:Momentary
;SGL
:Alternate action
;SIL
:Momentary illuminated

These families were branded either Clare or as Pendar (the latter being made in France, as shown in the ESM catalogue). No explanation exists for why both companies were making the parts separately.

Perhaps due to the reduced size of the switch, the feature set of low-profile reed is smaller than that of [[Clare/Pendar high profile reed]]. In particular, DPST is not supported (the part number field for the second pair of contacts is always zero) and alternate action and and illumination are not supported at the same time.

===Part numbers===
Part numbers follow the format:

:S'''F'''L'''TC'''0'''W'''

;F
:Switch sub-series; '''F''' = momentary, '''G''' = latching, '''I''' = momentary illuminated
;L
:Extra character to denote low-profile
;T
:Terminals and keystem
:*'''1''' = Sloped (upright keystem); 5 mm terminals
:*'''3''' = Stepped (angled keystem); 5 mm terminals
:*'''5''' = Sloped; 3.5 mm terminals
:*'''6''' = Stepped; 3.5 mm terminals
;C
:Contacts; '''0''' = No contacts, '''1''' = 1 form A (SPST NO), '''5''' = 1 form A with diode
;0
:Low-profile reed is SPST only, so this position is always zero
;W
:Operating force (weight); '''0''' = Fixed slider, '''1''' = 50 gf, '''2''' = 80 gf
