Two normally closed switches connected in parallel implement which logic function?

Explanation:
Two normally closed switches conduct when their control input is false. When they’re connected in parallel, the circuit provides a path from power to the output if either switch is closed. That means the output stays high unless both control inputs are true (both switches open). In other words, the output is 1 for all input combinations except when both inputs are 1, which yields 0. This exactly matches the NAND function. So the behavior is NAND: output is high unless both inputs are high.
